I've had higher than 80 on every subject on all my report cards. But a new teacher came to the school and now suddenly, only in her classes, I've gotten a 75. I hope the other teachers realize that it's not because I'm slacking off in my work, it's because she's not a very good teacher, and she marks way harder than the others. It bothers me but I can't tell my friends about it because they are below average regularly and think that me getting a 75 isn't a big deal, though to me it's really upsetting and stressfull
